Was she being rude

She admitted to going in my room to get something then she’ll tell me about how she found something and was asking me about why I have it. It shouldn’t be her concern. When I was younger and I told people she wasn’t good to be around they all ignored it years later all of them agree with me and even avoid her now. She’ll even say I’m a dirty bitch and that I have multiple STD meanwhile our mother told me that she was the one who always had infections and I never did. This morning she told me to stop using her hair products and to get that wig off my head because it’s summer now, go get some braids in your head. Meanwhile I don’t want to get braided.
